Effect of tillage system on growth, maturity and yield of corn and soybean
Entry ID: PU.Agronomy.TillageSystem

[ Update this Record ]

Summary
Abstract: This experiment was initiated in 1976. In the previous years
(1955-1975), the site had corn/soybean production with annual
moldboard ploughing. It is estimated that between 1880-1955 there
was mixed forage/grain production, ploughed two years in every five.
Before 1880 the site was in native prairie
grass.

Rotations used in this experiment are continuous ... View entire text

Quality There are at least 4 replicates in the experiment. The experiment has
a restricted randomized plot design. Split plot design with crop
rotation as main plot and tillage system as subplot. There are control
plots described as follows: Fall moldboard ploughing, most common
practice on this soil for the previous 100 years, was included as a
control. Yield data was analysed using Student-Newman-Keuls test and
coefficient of variation. Years was included as a fixed variable.
